Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626786, here are decompositions:

23 + 8626763 = 8626786
53 + 8626733 = 8626786
89 + 8626697 = 8626786
173 + 8626613 = 8626786
257 + 8626529 = 8626786
269 + 8626517 = 8626786
293 + 8626493 = 8626786
317 + 8626469 = 8626786

Showing the first eight; more decompositions exist.
